Barcelona plans to have established 191 charging points in the city by 2011.

Renault revealed four new electric vehicles at the Frankfurt motor show that will go on sale between 2011 and 2013. In August, Nissan unveiled its LEAF, the medium-sized hatchback destined to become the first mass-produced electric car.

Jordi William Carnes, a city of Barcelona representative, said: 'The zero-emission mobility programme is one of our commitments. When considering the population density of the city, there is a need for concrete actions to promote sustainability.'
